Ah Odai, back again I see, and still viewing with skepticism any advice tendered by these helpful posters.
To all of them, and you if you wish to take advice, PHOTOCOPY and keep separately every page of your logbook.
Don't hesitate to use more than one line to record details of flights, there is no requirement to be analy retentive, or tidy; and the more detail the more cherished will be your records. For example, recording weather conditions, instructors, challenges, landouts, crashes, etc etc. The more detail the better, and do NOT go back and copy everything over into a fancy professional book, that will definitely give an impression of doubtful veracity and posing.
